They did what they were supposed to. My problem arose when I had 20" drawers in a 23" deep cabinet and had to put 2x4 pieces in the back of the cabinet because I couldn't find longer brackets. The original staples were 5" deep for regular drawer slides, they say these new staples would fit up to 2-3/4" apart. they're not there, maybe 2-1/4 and they can hold on to the foil. Why don't they make longer braces?
